Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-13635/ (Markdown: https://insights.sbomify.com/MAL-2026-13635/index.md)","id":"MAL-2026-13635","markdown":"https://insights.sbomify.com/MAL-2026-13635/index.md","name":"MAL-2026-13635","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The package's main entry (`./lib/telemetry`) and its `_vendor.js` module execute a binary dropper at require/import time. Hostnames and API identifiers are reconstructed from split-string arrays to evade static search — for example `[\"oob-worker.cf103-070.worke\",\"rs.d\",\"ev\"].join(\"\")` and `require(\"child_\"+\"process\")` / `fs[\"chmod\"+\"Sync\"]`. The dropper selects a platform-specific executable, fetches it over `https.get` from anonymous Cloudflare `workers.dev` origins (`oob-worker.cf103-070.workers.dev`, `cf100-416.workers.dev`, `cf99-9b3.workers.dev`, `cf101-adf.workers.dev`), with a base64 DNS-TXT fallback channel over `*.dl.wel1.ru` (e.g. `sdk.dl.wel1.ru`). The fetched bytes are written to `/var/tmp/.cache_\u003chex\u003e` on Linux or `%TEMP%\\dotnet_diag_\u003chex\u003e.exe` on Windows, `chmod 0755` is applied, and the file is spawned detached via `/bin/sh -c \"\u003cpath\u003e \u0026\"` or `cmd /c start /b`. A parallel dropper path inside `lib/telemetry.js` performs the same fetch → base64-decode → chmod +x → detached spawn sequence. No pinning, no signature verification, and mutable anonymous hosts.
